Connecting the inverters
Suntechnics (only Solar-Log1000)
70 of 268 Solar-Log
1000/500/200
Installation
4.28 Suntechnics (only Solar-Log
1000
)
Note
Suntechnics inverters can only be connected to the Solar-Log
1000
, as only this
one has a CAN interface.
The following description relates to inverters without transformers produced in
or after 2007.
Overview
Can only be used on Solar-Log
1000
(CAN interface).
Interface integrated
Where to connect: CAN socket on the outside of the bottom of the in-
verter.
Only use ready-made cable sets.
Two different special cable sets must be ordered separately:
– Prefabricated cable set between the Solar-Log
1000
and inverter 1, in-
cluding cable termination.
– Ready-made cable set with 5 pin Phoenix contact connection plug for
connecting the inverters to each other.
Depending on the number of inverters several of these cables will be
required.
Max. total cable length: 500 m
Communication address does not have to be allocated.
Work steps
• Switch off the inverters and the SolarLog™; Page 17
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
Connecting inverters to the Solar-Log
1000
Connection is only done using a ready-made data cable, specially for connect-
ing to the Solar-Log
1000
(optional extra; not supplied).
Procedure
1 Insert the CAN plug into the inverter CAN IN socket.
2 If only one inverter is to be connected it must be terminated:
Insert the two 5 pin 120 Ω terminal resistors from the ready-made cable set
into the CAN OUT socket.
3 Insert the terminal block connector into the Solar-Log
1000
CAN socket.
